Wet and dry seasons are already part of the Aussie vernacular in most of the country. There's region specific lingo as well, except in Melbourne where there's just no point in trying to discern what season it is.
It gives me a chance to use a favourite new word I discovered recently...petrichor, which is the scent of rain on dry earth.

Thanks for sharing, it's nice to be able to name things you enjoy. That's a good one.
